SPECIFICATION forming part of Letters Patent No. 745,781, dated December1, 190 Application filed July 3. 1903. Serial No. 164,226. (No model.)

To all whom it may concern.-

Be it known that we, GRANT CAMPION and MoTT WYANT, citizens of theUnited States, and residents of Anderson, in the county of Madison andState of Indiana, have made a certain new and useful Invention inGas-Producers; and we declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters and figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a section on the line 1 1, Fig. 3. Fig. 2 isa section on theline 2 2, Fig. 3. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4 isa top plan view of the gas-producer. Figs. 5 and 6 are detail views ofthe grate.

The invention has relation to the manufacture of gas; and it consists inthe novel construction' and combination of parts as hereinafter setforth.

The apparatus or plant may be constructed in single form, or it mayconsist of several like apparatus connected in battery.

In the accompanying drawingsthe letter a designates the body of thegas-producer,which rests upon the corner-supports b, which projectsomewhat inward. In the construction shown the body is exteriorlycylindrical and its inner wall-surface is also cylindrical in its upperportion, this cylindrical inner surface being intersected at the lowerportion thereof by the interior shelving walls or faces, (indicated at0.) Below the inclined faces 0 the wallis sheer downward and in itsmiddle or bridge portion is provided with a flange cl, extending intothe water-bosh, while at its end portions, which are over thecornersupports, the inner wall extends downward to the grate-ledges e,which project inwardly in angular form, as above indicated. The flanges(I serve to provide, in connection with the plating of the angularprojections and the water in the basin f, a gas-tight joint.

At the corners of the lower portion of the inside wall of the body ofthe producer, extending downward from the intersections of theshelving-faces c to the supporting-ledges e, are the pyramidal angularridge-grates, located opposite and detached from each other in thecorners of the polygonal fire-box, into which they extend. Each grate isdouble, being composed of two triangular grates g, which meet alongtheir inclined long edges h, which have the sameor nearly the sameinclination as the shelving-faces 0. These grates incline downward andoutward from their meeting-line on each side to their lower edges it,which rest on proper bearings 01": the ledges e of the inner supportingprojections 11. The rear edges 1 of these grates are in approximatecontact with the wall of the body, and the pyramidal interval or chamber2 behind and under each grate, communicates with an opening m for theintroduction of air or steam through the wall of the body of theproducer, this opening being provided with a closing valve or gate 12. Asteam-conduit is also usually provided through this opening, as atp,where such steam-conduit is shown as a pipe-section connected to thegate.

The cavity of the basinf or water-bosh is branched or of crucial form,its branchest extending from the middle portion 1), where they are incommunication outward under the middle portions of the sheer walls belowthe shelving-faces c to the exterior or open portion of the basin. Theouter ends of the branches thave bottoms which slope gradually upward tothe margin of the basin and serve for the removal or manipulation of theash and cinder pile in the middle portion. Openings 3 are providedthrough the bridge portion of the wall over the branches 15, theseopenings being provided with proper valves or gates 41., which areconstructed with pokeholes 5. of the lower portion of the fuel-bed andfor the removal of any undesirable accumulations which may appear.

Through the cylindrical portion of the wall above the shelving portionor between these portions are made poke-holes 6, which serve animportant purpose in the reduction of clinkers and otherwisemanipulating the fuelbed.

The hopper 7 is formed in the upper portion of the body, beingpreferably in the center of the top wall and of square shape, conformingto the contour of the interior chamber of the producer, as such angularform will cause the fuel to bank toward the grates,

These openings serve for inspection ICC when it can be readily reachedthrough the top poke-holes 8 and evenly spread. Through the top are alsoprovided peep-holes 9 for the examination of the fuel-bed. The gasformed in the producer can be conducted off for use through the opening.2.

This producer is designed for the manufacture of gas from coal with theproportionate use Of Water and steam or air. The water bosh or basin andbody of the producer can be constructed of brick, proper jacketing ofmetal being provided where advisable. The outlets of the water-boshpoint in different ways, so that the operations upon the ash and cinderaccumulation in the basin are not confined to one point.

The form of the grates being pyramidal and increasing in area downwardand inward provide for the access of the greater portion of the blast ofair or steam through the heavier thickness of the fuel-bed, the lighterblast operating through the thinner portions in a graduated manner,whereby it is designed to avoid the production above the fuel-bed offlames, which would destroy the gas. It is also designed to avoid coldpoints in the fuel-bed, such cold places having the effect to cause thecoal to clinker and waste.

The triangular pyramidal grates are designed to provide, therefore, asuitable distribution of the air or steam necessary for gasification. Itis intended also to require a comparatively small pressure of steam tothe outlet-pipes, and in this way to maintain a cleaner gas-line andmore even distribution.

Having described this invention, what we claim, and desire to secure byLetters Patent, 1s

1. In a gas-producer, the combination with the shelving portions of theinterior wall, of the pyramidal ridge-grates, alined with said shelvingportions, substantially as specified.

2. In a gas-producer, the combination with the branched water-bosh, andthecorner-supports and ledges, of the pyramidal cornergrates on saidledges, substantially asspecified.

3. In a gas-producer, the combination with abranched water-bosh, andcorner-supports and ledges, of a body having downward and inwardinclined inner wall portions, and triangular grates on the ledges ofsuch cornersupports having similar inclination to said wall portions,substantially as specified.

4. In a gas-producer, the combination with the branched water-bosh, ofthe corner-supports and ledges, the grates on said ledges, and the bodyportion bridging the branches, and having down ward flanges at theirbridge portions, substantially as specified.

5. In a gas-producer, the combination with a branched Water-bosh, of abody having bridge portions,and corner-supports,iuclined grates on saidcorner-supports and shelvingwalls above the bridge portions,substantially as specified.

6. The combination with a gas-producer having a polygonal fire-box, ofcorner-grates detached from each other and extending into the fire-box,substantially as specified.

7. The combination with a gas-producer having a polygonal fire-box,ofpyramidal corner-grates detached from each other, and extending into thefirebox, substantially as specified.

8. In agas-producer,the combination of the corner-supports, a branchedwater-bosh between said supports, and pyramidal grates upon the innerends of said supports, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
